I have to say that I'm very new to these issues, if you support me, I can.
I have Armlogic S905X CPU 4 Core A53 Armcortex 2GB RAM + 32GB ROM mini Led Projector.
Android 6.0 is installed, but some applications do not accept. I can upgrade my projector to Android 7 and above.
I would be very happy if you help me with this, thank you.
